Chapter 8.1, Problem 6R

To determine

The amount by which the concentration of atmospheric carbon dioxide increases from 1958 to 2010.

Answer to Problem 6R

The amount by which the concentration of atmospheric carbon dioxide increases from 1958 to 2010 is $78\text{ppm}$ .

Explanation of Solution

Given info:

Concentration of atmospheric carbon dioxide in 1958, $C_{1958}=312\text{ppm}$

Concentration of atmospheric carbon dioxide in 2010, $C_{2010}=390\text{ppm}$

Formula used:

The expression to determine the amount by which the concentration of atmospheric carbon dioxide increases from 1958 to 2010 is,

  $\Delta C=C_{2010}-C_{1958}$

Calculation:

Substitute the given values in the above equation.

  $\begin{array}{c}\Delta C=C_{2010}-C_{1958}\\ =390\text{ppm}-312\text{ppm}\\ \text{=78}\text{ppm}\end{array}$

Conclusion:

Hence, the amount by which the concentration of atmospheric carbon dioxide increases from 1958 to 2010 is $78\text{ppm}$ .
